Comodo hogs 100% cpu

Issue:

Your computer is at a slow crawl and you are unable to do anything. This is because Comodo Antivirus is hogging CPU usage. If you look at task manager you will notice that either cpf.exe or  cmdagent.exe hog 100% CPU usage.

Fix:

  1. Reboot your computer in safe mode
    To enter to the safe mode, you need to press F8 button before Windows starts booting until you see the boot menu. In the boot menu, select the safe mode.
  2. Delete the file in c:\program files\comodo\comodo internet security\scanners\bases.cav
  3. Copy c:\program files\comodo\comodo internet security\repair\bases.cav to c:\program files\comodo\comodo internet security\scanners folder(this action will replace the current bases.cav file with the original bases.cav file that comes with the installation).
  4. Restart your computer and Update your virus database again.

Performing the 4 above steps should get your computer back to normal.

I found this fix on one of these forums posts linked here:
